Conventional aircraft, particularly military aircraft, may be equipped with mission-specific pods secured to an external surface of the aircraft. Mission-specific pods house various components or payload that facilitate the execution of various operations associated with a mission. For example, a mission-specific pod can include electronic components, such as antenna, that facilitate incoming and outgoing communications between the aircraft and any of various other objects. A mission-specific pod may also, or alternatively, include electronic components, such as radar and sensors, that facilitate surveillance operations.
Because different missions often require different operations, they also demand pods with different components to accommodate such divergent operations. Moreover, a single aircraft may be used to fulfill different missions. Accordingly, one aircraft may require complete removal of one pod associated with certain operations and attachment of another pod associated with certain other operations. The removal and attachment of traditional pods requires a complete removal of the entire pod from the aircraft, and a complete attachment of the entire pod to the aircraft. This removal and attachment constraint places practical limits on the size, shape, and modularity of traditional pod designs. Traditional pods utilize a standard mechanical and electrical interface with the aircraft, which also limits their flexibility and adaptability to diverse mission sets. Generally, customized pod interfaces have found limited use in the past at least partially because the processes for complete removal and attachment of customized pods are complicated, time-consuming, and costly. Further, many customized pods require extensive modifications to the host aircraft to accommodate customized interfaces. For example, the couplings that secure the pod to the aircraft may not be easily accessible during normal operations if customized interfaces are used to accommodate a larger pod capable of carrying a wider variety of pod mission systems. Overall, traditional pod designs face a tradeoff where they must contend with limited size and utility in order to obtain the ease of integration associated with standardized aircraft interfaces. Similarly, traditional pod designs face installation complexity and expensive aircraft modifications in order to obtain the flexibility and utility associated with customized interfaces.
Commonly, the internal components of a pod may need to be accessible while the pod is attached to the aircraft for testing, maintenance, or repair of the components. A pod may include side access ports through which an operator may access the components. Additionally, the components may be mounted to a panel that is removable from the pod for providing access to the components. Often, the panel containing the components is slid laterally or longitudinally out from the pod. Such lateral or longitudinal movement can be obstructed by other structures of the aircraft, such as landing gear and fairings.
Although some testing of the components of traditional pods can be performed through access ports while the components are installed within the pod, or by removing a component panel from the pod, such testing is limited. For example, only limited access to some components is allowed through the access ports. Accordingly, testing of only some of the components is feasible through the access ports. Even though removal of the component panel from the pod allows additional access to more components, because the component panel has been physically and electrically separated from the pod, testing of the entire pod, including the internal components and external components, such as sensors, radar, antenna, etc., is not feasible.
Requirements for maintenance access and removal of pod components, coupled with the complexities of surrounding aircraft components, dictate that traditional pods must be completely removed from the host aircraft in order to undergo significant testing, maintenance, or troubleshooting. Removal, transport, and storage of traditional pods require support equipment such as carts, hoists, and racks. Because a traditional pod must be completely removed from the host aircraft and then transported on support equipment, practical limits are placed on the size, shape, and weight of traditional pod designs.
